Problems solved by technology

[0003] There are many ways of failure of the fan in the farm, for example: the failure of the fan line causes the fan to be powered off and unable to rotate; the fan is damaged and cannot rotate; The louver of the fan is an integral part of the fan. If there is resistance and cannot be opened, it will also affect the ventilation effect
[0004] Although the current detection of the working status of the fan in the farm has fault feedback, it is all in the control equipment of the fan. It can only detect whether the feedback fan is powered on and whether it is working. As for the actual working effect of the fan, it cannot detect and feedback, let alone provide prediction. Prompts for permanent faults and maintenance of usage status

[0059] The fan current and voltage acquisition circuit is placed at the power supply line end of the fan to detect the fan's startup transient current and voltage, as well as the normal operating current and voltage;

[0060] The detection circuit is integrated on the PCB circuit board of the louver fan, and forms a blade attitude detection device with the three-axis acceleration ...

Embodiment 2

[0071] In addition, this application also provides a detection method and a prediction method for a louver fan in a farm, wherein: the detection method for a louver fan in a farm according to the present invention includes the following steps:

[0072] Step 1: Detect whether the louver fan is activated, including two situations:

[0073] Case 1: Detect whether the fan is started: obtain the instantaneous current and voltage of the fan through the fan current and voltage acquisition circuit, and make the following judgments:``

[0074] If the fan current and voltage acquisition circuit can obtain the instantaneous starting current and voltage, then continue to compare and judge with the historical data:

[0075] If the instantaneous current and voltage are consistent with the historical data, proceed to step 2;

[0076] If the instantaneous current is more than 30% larger than the historical data, and the voltage is lower than 30%, it is judged that the fan is abnormal, and an...

Embodiment 3

[0098] The prediction method of the louver fan in the farm according to the present invention, according to the large database of historical data, constructs the prediction model of the fan and the louver, judges that the fan and the louver are in the stage of the prediction model, and the server advances the predictive guidance conclusion It is transmitted to the control device or environmental controller of the louver fan through the wireless communication module.

[0099] The maintenance method of the louver fan in the farm according to the present invention, the instantaneous process of the starting current detected by the current and voltage acquisition circuit of the fan can determine the aging degree of the fan, the real-time detection of the normal operating current and voltage of the fan, and the spectral analysis and Time domain analysis judges the problem of normal operation of the fan;

[0100] The instantaneous opening angle detected by the three-axis acceleration...

Description

technical field [0001] The invention relates to a louver fan system for a farm and a detection and prediction method thereof, belonging to the technical field of farm detection. Background technique [0002] At present, in the large-scale and centralized breeding environment, the environmental control requirements in the farm are getting higher and higher. Among the various environmental parameters in the farm, the temperature, respiration and ammonia concentration of the farm are the most important. important. These three parameters are all achieved by controlling the ventilation effect. At present, all the environmental controllers of the farms use fans installed in the farms to solve the temperature control and ammonia concentration control of the farms. Therefore, whether the fan works normally directly determines the quality of the environmental parameters of the farm. When the fan fails, it is directly related to the mortality of poultry and the economic loss of the ...
